ABSTRACT OF THE DISCLOSURE In a coin packing machine wherein a stack ofa predetermined number of coins is packed by wrapping a wrapping paperaround the stack, a number of coils of wrapping papers of differenttypes are mounted on a rotary disc, and when a particular type of thecoin to be packed is selected, the coil of the wrapping papercorresponding to the selected type is brought to the operating position.

BACKGROUND OF THE INVENTION This invention relates to a wrapping papersupply device for automatic coin packing machines.

PRIOR ART In a well known coin packing machine, coins are successivelystacked flatwisely to form a cylindrical stack. Upon reaching apredetermined number, the stacking of coins is stopped, a length ofwrapping paper having a width slightly larger than the height of thestack is wrapped around the stack, and then opposite ends of the wrappedpaper are folded to securely hold the packed coins. The surface of thewrapping paper is printed with words representing the number and type ofthe coins contained in the package. In addition, the width of thewrapping paper should be varied in accordance with the type of the cointo be packed. For this reason, where various types of coins are to bepacked by the same packing machine, it is necessary to prepare varioustypes of wrapping papers corresponding to the types of the coins. Inprior automatic coin packing machines, whenever the operation of themachine is switched from one to another type of coin it is necessary tomount a particular type of wrapping paper corresponding to the selectedtype of coin.

This is of course troublesome and decreases the operating speed of thepacking machine.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to theaccompanying drawing, the novel wrapping paper supply device for coinpacking machines comprises a horizontal rotary disc 3 supported by avertical shaft 2 rotatably journalled by a stationary machine frame 1and a plurality of cylindrical holders 5 secured to the upper surface ofrotary disc 3 to support rolls of webs of wrapping papers 4 havingdifferent widths and printed words dependent upon the type of the cointo be packed, said holders 5 being uniformly spaced along a circle onrotary disc 3. At one side of each roll 5 are provided a verticaldriving roller 6 and a pinch roller 7. As shown in FIG. 2, the lower endof the driving shaft 8 of each driving roller 6 is projected beyond thelower surface of rotary disc 3, wherein a serrated clutch member 9 ismounted on driving shaft 8. Another serrated clutch member 10 adapted toselectively cooperate with one of said clutch members 9 is mounted on ashaft 11 by means of a pin and slot connection (not shown) to be movablein the axial direction of shaft 11 which is rotatably journalled onmachine frame 1.

Clutch member 10 is provided with an annnular groove 12 on its peripheryto receive a lever 13 actuated by an electromagnet, not shown. Shaft 11is driven by an electric motor 16 through a belt 14 and a pulley 15.

On one side of each of driving rollers 6 and on the upper surface ofrotary disc 3, there is provided a cutting knife 17 having a V-shapedcutting edge directed toward driving roller 6. The rotary disc 3 isdriven by an electric motor 18 through a driving roller 19 in contactwith the peripheral surface thereof.

A switch operating cam 20 is mounted on driving shaft 2 of rotary disc 3to operate actuating member 22 of respective switches 21 correspondingto the type of coins or type or width of the wrapping paper 4.

Cam 20 is provided with a plurality of offset portions 23 adapted toengage respective actuating members 22 of respective switches 21 toactuate the same. Switches 21 are connected in parallel, as shown inFIG. 3, and are respectively connected in series with an electromagnetor solenoid 26 arranged to operate a locking bar 25 adapted toselectively engage one of spaced openings 24 through rotary disc 3, eachone of said openings being provided for each type of coin. Switches 21are also connected in series with driving motor 18 of rotary disc 3.

The operation of the wrapping paper supply device embodying thisinvention is as follows:

In operating a coin packing machine, not shown, the machine is set for aparticular type of coin by operating a selector knob. Responsive to thisoperation, an operating shaft (not shown) is rotated to adjust the widthof a coin passage, which successively sends out a counted number ofcoils selected to a packing mechanism, to a value corresponding to thediameter of the selected coin. Further, in response to the rotation ofsaid operating shaft the position of edge folding levers (not shown) isadjusted to generally correspond to the height of a stack of apredetermined number of the coins selected, said levers acting to foldopposite edges of the wrapping paper that has been wrapped around thestack of coins. Since the above described operation of the coin packingmachine and the constructions thereof are well known in the art, furtherdescription thereof seems unnecessary.

A rotary switch 27, shown in FIG. 3, is arranged to be rotated inresponse to the rotation of said operating shaft of the packing machine.Stationary contacts 27a of rotary switch 27 are respectively connectedto switches 21 so that motor 18 and electromagnet 26 are energizedthrough one of the switches 21 corresponding to the selected type ofcoin. Then locking bar 25 is withdrawn from opening 24 of rotary disc 3,while at the same time the rotary disc is rotated by motor 18 through adriving roller 19. Although not shown in the drawing, switches 21 mayalso be connected to light pilot lamps that indicate the type of coinselected. As rotary disc 3 rotates, its shaft 2 will rotate cam tosequentially operate switches 21. When a particular switch 21 that hasbeen selected in accordance with the selected type of coin to energizemotor 18, and electromagnet 26 is opened by a corresponding actuatingportion 23 of cam 20, motor 18 and electromagnet 26 are deenergized tocause locking bar to engage a selected one of openings 24, thus stoppingthe rotation of rotary disc 3. Then a particular coil of the wrappingpaper corresponding to the selected type of coin will be positionedclose to a packing mechanism (not shown).

When a predetermined number of counted and successively supplied andpiled up coins are in the packing mechanism of the machine, anelectromagnet (not shown) is operated to attract lever 13 received inannular groove 12 of clutch member 10 to move it upwardly to engageclutch member 9. Since clutch member 10 is normally driven by electricmotor 16, coupling between clutch members 9 and 10 causes a drivingroller 6 for a particular wrapping paper 4 for the selected type of cointo be driven. Thus, the driving roller 6 cooperates with pinch roller 7to supply the web of wrapping paper 4 to the periphery of the stackedcoins. At the moment when wrapping paper 4 is wrapped around the stackof coins, a tension is abruptly applied to the wrapping paper so thatthe paper will be cut into a predetermined length by cutting knife 17.After a predetermined length of wrapping paper 4 is sent out, motor 16is stopped. Upper and lower edges of the paper wrapped around thestacked coins in the form of a cylinder are folded by said foldinglevers, thus completing the packing operation.

In the manner, in response to the selection of the type of the coins tobe packed, rotary switch 27 is operated to connect one of the switches21 corresponding to the selected type to one side of an electric source,and when this switch is closed, motor 18 and electromagnet 26 areenergized to operate locking bar 25 and motor 18, whereby rotary disc 3is rotated to bring a particular coil of wrapping paper 4 supportedthereon and corresponding to the selected type of coin to the operatingposition in which the paper is supplied to the packing mechanism asabove described. Concurrently therewith, clutch members 9 and 10 arecoupled together to supply the selected wrapping paper to the packingmechanism.

FIG. 4 shows a modified arrangement for operating switches 21. In thismodification, instead of cam 20 mounted on the shaft 2 of the rotarydisc 3, a plurality of switch actuators 23a, in the form of round-headscrews, for example, are secured on the lower surface of rotary disc 3at different radial distances from the axis of rotation thereof. In thecondition shown in FIG. 4, right hand switch 21, is held closed toenergize electromagnet or solenoid 26 and disc driving motor 18.However, when rotary disc 3 rotates to a position to bring the selectedcoil of the wrapping paper to the operating position, said switch 21will be opened by the cooperating switch actuator 23a to deenergizemotor 18 and electromagnet 26.

Thus, according to this invention, whenever the coin packing mechanismis operated to select any desired type of coin, a wrapping papersuitable for said selected type is automatically selected and fed to thepacking mechanism, thus improving the packing efiiciency as comparedwith the conventional packing machine wherein each time the type of thecoins is changed from one to another, it was necessary to select a coilof wrapping paper suitable for the selected type and to mount said coilon the packing machine. Further, the positioning of the rotary discsupporting coils of wrapping papers can be effected accurately by therotary disc driving motor controlled by a rotary switch responsive tothe selection of the type of coin and a plurality of switches arrangedto be selectively operated according to the rotation of the rotary disc.Thus, the selected coil of the wrapping paper supported on the rotarydisc is automatically brought into the operating position and is thenpositively supplied to the packing mechanism by the driving roll, whichis driven through a coupling clutch.

While in the foregoing embodiments, the rotary disc adapted to supportcoils of wrapping papers was shown as a horizontal rotary disc, it willbe apparent that the rotary disc may be installed in a vertical orinclined position with respect to the packing mechanism. Alternatively,a reciprocating wrapping paper holder may be substituted for the rotarydisc.

While in the foregoing description the invention has been shown anddescribed in terms of preferred embodiments, it will be clear to oneskilled in the art that many changes and modifications can be madewithout departing from the scope of the invention as defined in theappended claims.
